Using the free version 22.214.171.1244 on Windows 7 SP1. There are some problems when attempting to update the definitions. They don't occur every time, just randomly:
1- When updating is finished, the blue process bar won't disappear. No problem when restarting.
2- When going directly to "Scan now", it stucks while applying updates, so it never starts scanning.
I noticed this behaviour on several machines (Windows 7+Vista) with versions 2.x installed. No similar problems when using v. 1.75.
Any experiences? Thanks.
